>Hi. I'm new at VFP6 and want to do something clever but don't have the foggiest clue how to accomplish this. I have a report driver screen that lists a number of reports and allows the user to select the appropriate report. (So far so good...) Once the user highlights the report title I want to display options on the lower portion of the screen. These are report specific options and I would like to put the code (that builds the objects - like a date range, or a picklist) into a database and extract the code from there. I figure that way I will only have to code one screen and whenever I add a new report, I will only need to add the code into that database. I know it must be possible to do since VFP is all databases anyways but can anyone tell me how to do this?? (I'm slow so explain in fairly good detail.)

Sandi,
You have two options:
1) Build your code and evaluate it at runtime using macros (&) or the EVAL() function. This only works if you are doing one expression or command at a time.
2) Even better if you add VS patch SP3: You can use COMPILE to compile code on the fly. If your code is in a database (Memo field maybe), you must first write it out to a file (using SET ALTE TO or FCREATE/FPUTS) and COMPILE. Then you can use the DO
to execute it.
